注大乘入楞伽經 1.153

1.153

問：何故說此五喻？為顯諸法本離生滅，興此喻也。如下，沙門婆羅門，觀一切法無自性中別答。

This asks: Why are these five similes spoken? These similes are raised to reveal that all phenomena are fundamentally free from arising and ceasing. This is answered individually below, under the śramaṇas and brāhmaṇas contemplating that all phenomena lack intrinsic nature.
